WRENCH MECHANISM.

Application filed November 8, 1924. Serial No.1'748,569.

This invention is applicable to three types of wrench, viz

, a socket wrench adapt-ed to receive a polygonal nut, a plug wrench adapted to enter a. polygonal socket in a and a. pipe wrench adapted to engage androtate a cylindrical object.

The object is nism or outfit provide himself-with either of twoone adaptedto serve either as a wrenches,

socket wrench, or as a plug wrench,

e either as a. plug wrench or as other to serv a gipe wrench.

to provide a wrench mechafrom which the owner can duplex and the he wrench mechanism above mentioned includes three elements, on-e of which is a.

stock having a fixed wrench jaw, while the others are movable jaws, adapted to be used interchangeably with the stock, movable jaws and the duplex wrench, external sur face of a nut, or

one of the stock constituting a adapted the internal surface of a plug-socket, while the other movable jaw and adapted to engage either the plex wrench, internal surface ripheiy of a cyl the socket constitute a duof a plug socket, or the peindrical pipe.

Of the accompanying drawings forming a part of Figures 1, 2

the component parts or this specification,-

elements of a wrench mechanism embodying the invention, Figure 1 showing the worm,l Figure 2, the

The `fixed jaw 12 isv The fixed jaw `has a' 18, adaptedto conin an externally threaded plug 22, shown inV Figure 9 by dotted lines.`

' The stock in the condition Figure 1, is adapted to cooperate with either of the movable jaws shown by Figures 2 and 3. 1

The movable jaw has inner and outer faces 18a vand20, corresponding to the faces 18 Aand this movable jaw and. the fixed jaw i are adapted to cooperate either in engaging nut 19, or a plug 22.

The movable jaw has an inclined inner cheek, formed by a series of teeth 25, adapted to engage one side of a pipe 26, and a salient outer cheek 20", corresponding to the salient cheek the fixed jaw, so that this movable jaw and the fixed aw are adapted to cooperate either in engaging a pipe, as shown by Figures 6 and 7, or a` socket 21, as shown by Figure 9.

Each movable jawis provided at its inner end with a post 26, formed to slide endwise Without turning in the guide 14, and arranged at right angles with the jaw. On
